ReadBits - Learn To Code - PlayBASIC Documentation

ReadBits

Result = ReadBits(SrcValue, Startbit, BitCount)

Parameters:

    SrcValue = The source value to read bits from
    Startbit = Bit from where to start
    BitCount = Number of bits to read

Returns:

Result

The ReadBits returns a range of bits defined by StartBit and BitCount from SrcValue.

Mini Tutorial:

Showing the use of the function ReadBit

; assign values to variable SrcValue
  SrcValue=$AABBCCDD

; Return 8 bits starting at bit 16
  Print Hex$(ReadBits(SrcValue, 16,8))

; Return 16 bits starting at bit 32
  Print Hex$(ReadBits(SrcValue, 32,16))


; Display the output and wait for key.
  Sync
  WaitKey

This example would output.

  $CC
  $AABB
